It seems the latest firmware release fixes the display problem, or is it just a temporary fix to extend the display life?When i get my GH-505, should i immediatly update the firmware to prevent the display problem?Will i need to return it to exhange the display when the new model is available?

Thank you

Dear customer,

Thanks for using our product.You can get it to experience first. And should update firmware before getting use.If you are not satisify, you can contact dealer.

Just started to have same issues (dead pixels) - although I used my GH-505 mostly while running and I was powering it off after finished. Sportracks say that i used it for ~600km. I tried to avoid keeping it in watch mode - it spend in that mode maybe 48-72 hours during it's life.

I've tried to update firmware after these pixels showed up, but of course it did not help - as it seems that it is hardware issue...

Could you please advice what should I do? I've bought it on auction service - although I have invoice from company which sold me that device... also I doubt it will be easy to replace by contacting them, also i don't think that there is officiall dealer in Poland...

Dear Arek,

It is bad to know you encounter problem.Can you please give me a photo and series number?

Today I did 1 hour jog at -15C - and magic - these dead pixels are gone. I wonder how long it will last - but for now I'm happy ;). While running, GH-505 was mostly showing heart rate at full screen and I've used backlight several times. And here are picures - with dead pixels and with pixels gone.

Before (few dead pixels):

After (screen seems clean):

It is real amazing! I never heard from supplier and it is difficult to reproduce in my side due to it is never so cold. Anyway, please take care your body.

Yesterday, we put other three spot watch into ice box under zero degree, power off ones got recover faster than power on. So I agree that cause by temperature.So we might call GH-505 as "arctic" watch.

My GH-505 start to have dead pixels as well. It stated suddenly (after half year usage without this problem) and now it is pretty bad.I have to freeze it after every training. It is pretty good for while but during longer train (>2h) it become quite bad again and it is very hard to read it.

Have you found solution how to get rid of this problem permanently or is it just hardware (on display itself) problem?

Rookie

How about this issue, any news regarding it?

Do you have any spare display available? I can change that display by myself if you have one for me.
